What you can expect with air-cooled gas coolers from Sterling Thermal Technology
As a leading UK designer and manufacturer of air-cooled gas coolers, Sterling Thermal Technology’s products offer exceptional performance:
Our designs meet the highest pressure requirements, whether it is for a gas compression cycle or other gas cooling applications. In all cases, we consider PED requirements section by section.
Optimum header designs
We use tubular or box header arrangements, depending on the pressure and dimensional configuration of the cooler.
Where the cooler is to be integrated with your equipment, we will closely work with you on the designs to obtain the most beneficial arrangement.

Technical design of gas coolers
For gas-to-gas heat exchangers, one of the most important factors is the pressure of the gas stream. Is it low, medium or high-pressure? This impacts the design of the cooler to ensure it fits its purpose.
At low pressure, the gas side heat transfer coefficient is, generally, low because the gas density is also low. Tube inserts can enhance the heat transfer coefficient if specifications permit.
In applications with medium gas pressure, the increased density of the gas leads to increased heat transfer coefficients. The optimum design requires less tube-side coefficient enhancement.
At high pressures, the mechanical design of the cooler becomes a more significant issue. Thus, Sterling TT designs the high-pressure cooling sections for pressures over 5,600 bar. At these pressures, the heat exchanger is a fully welded construction with thick wall tubes.
For compressor systems, the excess heat generated during the compression cycle must be dissipated. The cooler is split into several stages, each operating at differing tube-side pressures. The cooler stages are mounted in series; each has a different mechanical design pressure, but all have similar cross-sections for the cooling air path.
We work with you to design the best gas cooler for your process.
